Secret component to make spray dough
I have never even heard of spray dough, but you could make a filo dough roll it out thin with a pasta machine and drape it over a shape and then attempt to bake it as long as the shape can withstand the heat. Or you could let the dough dry a bit and it may retain its shape after you pull the mold out for baking. Any decent bread dough recipe should work as long as the gluten content is high enough to withstand the pasta machine and molding process. Although you could take a paper mache approach and use thin dough strips. 

Maybe if you can tell us more about what your end product should be we can help you get there.
