In the Byzantine Rite, there is a whole Office of Holy Communion. I try to same some part of it, usually the psalms and soem of the prayers.
The stucture is:
Introductory prayers (we say prayers before we pray

)
Psalms 21, 22, 23, 115 (Septuagint numbering)
Troparia before Communion
Psalm 50
Canon before Holy Communion (or Canon to our Sweetest Lord Jesus, a conon to the Theotokos, and a canon to one’s guardian angel)
It is truely Proper… (a common hymn to the Blessed Mother)
Trisagion prayers (these are like the intro prayers)
Troparion of Holy Thursday
Lord have mercy 40x, then 15 bows.
Precommunion prayers (there are at least 18)
Nicene Creed
Kontakion "Of thy mystical supper) (i think this is also of Holy Thursday)
Prayers upon approaching
Prayers after Communion
In Christ,
Adam
