In a large bowl combine shrimp, smoked paprika, cumin, garlic powder, onion powder, salt, chili powder, pepper, lime juice, lime zest, tequila, minced jalapeno and 1 tablespoon olive oil. Set aside.
Heat a large skillet over medium-high heat. Once hot add 1 tablespoon oil. When the oil just beginning to smoke add the shrimp in one layer in the pan.
Cook shrimp for 2 minutes, flip and cook 1 minute on the other side. Remove from hot pan to a clean plate.
Heat 1 tablespoon of oil in the pan, once hot add the garlic and onion and saute for 1 minute. Add mushroom and saute 1 minute, then add 1 tablespoon oil to the pan. When hot, add the bell peppers and stir occasionally -- about 2 minutes.
Add shrimp back to the pan, cook stirring for 1 minute to warm the seafood. Season fajitas with more salt and pepper as desired. Garnish with cilantro.
Serve spicy shrimp fajitas hot with warmed tortillas and lime wedges.
