In a large bowl, mix flour, salt, and baking powder.
Add vegetable oil and mix until crumbly.
Gradually add warm water, mixing until a dough forms.
Knead the dough on a floured surface for about 5 minutes.
Cover the dough with a damp cloth and let it rest for 15 minutes.
Divide the dough into 8 equal pieces.
Roll each piece into a ball and flatten it with a rolling pin.
Heat a skillet over medium-high heat.
Cook each tortilla for about 1 minute on each side, until lightly browned.
Keep cooked tortillas warm in a towel until ready to serve.
