I don't know, I think a lot of them do have egg (one's I've seen do). I have heard that in some asian groceries there are brands of wraps for certain kinds of buddhists who don't eat eggs. But I cannot confirm this.
When I wanted to make vegan samosas, I used vegan tortillas. Not the same thing, but if you are going to fry or bake them, they come out very similarly. Of course you couldn't use tortillas to make won ton soup!
