In a small bowl, combine the bang bang sauce ingredients and set aside.
In a medium bowl, mix together the shrimp with buttermilk, garlic powder, onion powder, and black pepper. Let it marinate for 10 minutes.
Place the cornstarch in a shallow dish. Working one at a time, remove the shrimp from the marinade, letting any excess drip off, then coat it in cornstarch. Transfer to a baking sheet. Repeat with the remaining shrimp.
In a large pot or Dutch oven, heat 1-2 inches of oil to 350°F. Fry the shrimp in batches for 2-3 minutes, until crispy and golden brown. Transfer to a paper towel-lined plate to drain excess oil.
In a large bowl, toss the fried shrimp with ½ of the bang bang sauce.
To assemble a taco, heat corn tortillas on the stove or in the microwave. Add 3 shrimp per taco and your desired toppings. Finish with a squeeze of lime juice and more bang bang sauce. Enjoy!
