Basically, the Typika is the (psalm-centric) beginning of the full, festal Divine Liturgy.
When it's done alone (at least in a monastic setting), it adds a few things to the Typika as chanted during the Divine Liturgy and goes like this: It's all of Psalms 102 (Bless the Lord, O my Soul), 145 (Praise the Lord, O my Soul), O Only Begotten Son, & the Beatitudes. Then it skips to the Creed, the Our Father, the hymns of the day, then Psalm 33 and the "Through the prayers..."
That's basically it. A few other hymns here or there. Sometimes people tack Scripture readings on to it, but I've never actually attended one with Holy Communion. Suppose it is possible, but, in that case, the Deacon would really just be communing people from the Reserve Sacrament -- as if visiting people at the hospital -- as an add-on ceremony.
Edit: Adding Holy Communion doesn't make sense according to the original purpose of the Typika (which was used in monasteries on days where there wasn't a full Divine Liturgy with communion, especially during Great Lent, wherein normal Divine Liturgies are not allowed on weekdays), but it makes sense in modern parochial settings, if the priest is away and the Bishop gives his blessing. Makes more sense to bring in one of the retired clergy from the diocese (that's what we do), but that's not always practical in areas without much Orthodox presence.
