There are tons of different types of orchids out there. I can't help you on specifically what orchids are good for your setup since I too am about to do the same.
Actually according to the book ORCHIDS a practical handbook, by Brian and Wilma Rittershausen, the following list of orchids do well in glass tanks.
Coelogyne coyrmbosa
Cirrhopetaum guttulatum(I've seen this genus being sold for vivariums too)
Dendrobium cuthberstonii
Encyclia polybulbon
Masdevallia Whiskers (I've got a M. rolfiana in a 29 gallon viv, but it hasnt bloomed yet, but Masdevallias are recommended as terrarium orchids)
Masdevallia towarensis
Mexicoa ghiesbrechtiana
Neofineta falcata
Oncidium cheirophorum
I've got a Haraella odorata in a 55 gallon vivarium that is going to bloom, but this is a mini mini orchid, don't know if thats what you are looking for.
Hope this helps,
here is a link to an online orchid seller that allows you to search orchids according to the growing conditions you can give them. Use the power search
