Get your toppings ready first and make sure the shrimp is completely thawed, peeled, and deveined if needed.
In a small bowl, mix together the garlic powder, onion powder, smoked paprika, ground cumin, chili powder, salt, and black pepper.
Add the shrimp, olive oil, and spice mixture to a large skillet heated over medium-high.
Toss the shrimp in the spices for about a minute to coat them evenly, then cook for 5 to 6 minutes, stirring occasionally until they turn pink and are cooked through.
Serve the shrimp immediately with warm flour tortillas and your favorite taco toppings.
