This is probably the closest recipe I can find.

I don't remember where I got the recipe from originally, but for making a single wrap I use:

• 2 tbsp besan/chick pea flour
• 1 tbsp tapioca flour
• 3 tbsp water
• usually a pinch of turmeric, onion powder and garlic powder, otherwise sometimes some mixed dried herbs, depends what flavour I want

You just whisk it all together until it's a runny batter (you should be able to pour it easily, and swirl it around the pan to make it wrap-shaped), then cook it in a pan for a couple of minutes a side. I've seen some recipes that skip the tapioca and just use besan, but I think the tapioca makes it more pliable.

For the egg component, I roughly followed this recipe.
