The Tabernacle is where God's people are to meet with Him. In the OT it was a tent, but today it is us, the individual believer, because He dwells in us by His spirit. I found no prayer of the tabernacle in the OT. So let me put this to you for your consideration. If we are the tabernacle because His spirit is in us. Then the prayer of the tabernacle would be spiritual. The only spiritual prayer, that I know of, is speaking in tongues. It is prayer between God and His spirit he has put within us. A very special way to fellowship with Him. Oh how the Lord longs for this prayer, it is rightous, it is perfect not contaminated by our worldly thoughts, yet it is from us via His spirit in us.
Please, in your considerations, do not let traditions or mens words (including mine) sway you. But rather search the scriptures to see if these things are true. Let God's Word speak for itself.
Below are some scriptures on the subject. We live is the age of Grace which started at Pentecost. God's rightousness is the same today as then and so are His gifts to the Church, which is the body of Christ.
2 Cor 5:1-10
5:1 For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens.
2 For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven:
3 If so be that being clothed we shall not be found naked.
4 For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.
5 Now he that hath wrought us for the selfsame thing is God, who also hath given unto us the earnest of the Spirit.
6 Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord:
7(For we walk by faith, not by sight
8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
9 Wherefore we labour, that, whether present or absent, we may be accepted of him.
10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad
Col 1:25-27
25 Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God;
26 Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
27 To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:
1 Cor 14:2
2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries
1 Cor 14:4
4 He that speaketh in an unknown tongue edifieth himself;
1 Cor 14:5
5 I would that ye all spake with tongues,
1 Cor 14:37-40
37 If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord.
38 But if any man be ignorant, let him be ignorant.
39 Wherefore, brethren, covet to prophesy, and forbid not to speak with tongues.
40 Let all things be done decently and in order.
Rom 8:10
10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
KJV
Rom 8:26-27
26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
27 And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.

1 Cor 14:15-18
15 What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
16 Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen
at thy giving of thanks, seeing he understandeth not what thou sayest?
17 For thou verily givest thanks well, but the other is not edified.
18 I thank my God, I speak with tongues more than ye all:
