How to make pancakes/crepes without eggs nor any liquids besides water? I am looking for a way to make pancakes/crepes (the very thin ones), with the following limitations:


no eggs
no liquid ingredients besides water
cheap ingredients only


I've been trying something like:


360 g wheat flour
40 g corn flour
850 g water


But the problem is that they turn out non-baked inside and too crispy on the outside, besides being too thick. I've been trying on lower heat, but then it takes like over 5 minutes for each pancake, and the inside is still not baked. I read that it should take 1 minute to bake 1 pancake.

Any changes to the ingredient list, or tips for baking procedure? What might be the problem that it takes so long, and the inside gets not-baked? I try to pour the batter on the pan as thin as I can, swiping the pan with a sponge made of toilet paper dipped in rapeseed oil before each pancakes, and its a thin-edge pancake Teflon-coated pan.



OK, maybe some clarifications: I am not vegan and have no allergies.
The motivation is completely different: life on the road and for extended periods away from any sources of anything other then tap water. 

The motivation is decreasing the weight and volume of stuff I need to take with me. Liquids are not good because they are heavy. Unless I need really little of them. But even then once I open the carton I probably need to use it up quick, because no fridge available.

So I am looking for ways of making pancakes out of ingredients which take up little volume and weight, and added to water can improve my pancakes. Powders are good, provided I have to add little of them. Also it has to be as low-budget as possible. Corn flour is cheap, baking powder is cheap, things like soy milk are not cheap.
Given your updated criteria, what about using powdered milk for crepes and pancakes?  Powdered milk tends to be very inexpensive.  You can usually find in in the baking aisle at groceries in the U. S.  The powdered milk will last you for a long time.

You can also get powdered eggs.  Just google for them.

As Martha astutely commented below, look for recipes for pancake mixes that require adding only water and pack those.
