Add the flour, yogurt, and salt to a large bowl. Using a silicone or wooden spoon stir until combined. Add 1 tablespoon of water at a time until a ball starts to form.
Transfer the dough to a floured work surface and knead until smooth. You may need to sprinkle more flour if the dough is too sticky.
Divide the dough into 8 pieces. Roll each piece into a ball. Flour the work surface, and then roll out each tortilla into a circle using a rolling pin until paper thin. You may need more flour during this step. Repeat until all the tortillas are rolled out.
Heat a large cast iron skillet over medium heat and spray with cooking spray.
Place one tortilla in the skillet and cook until it starts to bubble about 1 minute. Spray the top with more cooking spray then flip and cook for an additional 30 seconds to 1 minute.
Remove from the skillet and store in a folded cloth towel. Continue cooking the remaining tortillas.
