Add the tempeh, ½ Tbsp of olive oil, garlic, cumin, chili powder, onion powder, smoked paprika, salt, and black pepper into the bowl of a food processor. Pulse everything in the food processor until it resembles coarse ground meat crumbles. This will be your taco meat.
Heat the remaining olive oil in a large skillet over medium high heat. Add the tempeh taco meat into the skillet and cook for about 6-8 minutes, until it starts to turn brown and crispy.
Stir in the tomato sauce and cook for another 2-3 minutes. Transfer taco meat to a bowl if consuming immediately, or allow to cool and then transfer to an airtight container if you plan on eating it later.
To assemble the tacos, slightly heat up your corn tortillas over a low flame on the stove. Spoon about ¼ cup of taco meat into each tortilla. Finish off with toppings of choice and dig in!
