Put the flour, baking powder, and salt in a large bowl and mix together.
Add the vegetable oil and mix in.
Gradually add the hot water, mixing until a sticky dough forms.
Knead the dough for about 5 minutes until it becomes less sticky.
Cover the dough and let it rest for 30 minutes.
Divide the dough into 12-14 equal pieces and roll each into a ball.
On a lightly floured surface, roll out each ball into a thin tortilla.
Cook the tortillas on a hot griddle or skillet for 10-12 seconds per side.
