Spray your air fryer basket with cooking spray and preheat your air fryer to 400 degrees.
Pat your shrimp dry with paper towels and place in a large bowl. Toss with the oil and set aside.
In a small bowl, combine salt, chili powder, garlic powder, onion powder, cumin, and smoked paprika. Add to the shrimp and toss until the shrimp is evenly coated.
Carefully place the shrimp in a single layer in your air fryer basket (you may have to do this in batches), and air fry at 400 degrees for 4-5 minutes, or until the shrimp is cooked through to 120 degrees. Set the shrimp aside on a plate.
Wrap your tortillas in aluminum foil and place them in your air fryer basket. Air fry for 2-3 minutes at 400 degrees until they’re warm. Remove the foiled-wrapped tortillas from the air fryer basket and set on a plate.
Assemble the tacos with warm tortillas, shrimp, and toppings!
