Combine all the ingredients until the dough comes together in a ball - a Kitchen Aid with the paddle attachment is useful here. Add more yogurt if the dough seems too dry or more of the flours if it seems to wet be careful not to make the dough too wet so it is hard to handle).

Roll out about 1/6th of the dough for each tortilla, to a thickness of about 1/4" Rolling out the dough between 2 pieces of parchment paper will make things easier. 

Fry on a dry skillet until golden on each side.
