Peat moss, compost or aged stable manure or a mixture of the three with your soil.
You need to add some sand. Peat, Humus, top soil, etc will only create a very moist environment and will hold moisture. Perlite and Vermiculite are used to encourage good drainage and to keep the soil from compacting, which plant roots definitely don't like. I have not grown Lucky Bamboo, but do you know what kind of conditions it wants it's roots to be in?
The first answer lists things for retaining water rather than increasing drainage. Coarse grit or horticultural sand will aid drainage.
