Prepare the cilantro lime rice. While the cooked jasmine rice is still warm, stir in butter, lime juice, cilantro, and salt. Mix well and keep warm.
Make the mango salsa. In a mixing bowl, combine mangoes, cherry tomatoes, red onion, jalapeno, cilantro, lime juice, and salt. Gently mix and set aside.
Season the shrimp. Add shrimp to a bowl with olive oil, garlic powder, onion powder, paprika, chili powder, salt, and black pepper. Mix until evenly coated.
Heat a large skillet over medium high heat. Cook shrimp for 1 to 2 minutes per side until pink, opaque, and lightly caramelized. Remove from the skillet immediately.
Warm the corn tortillas in a dry skillet until soft and flexible. Keep covered until ready to serve.
Assemble each taco with shredded lettuce, pan seared shrimp, and mango salsa.
Serve with cilantro lime rice, lime wedges, and extra cilantro if desired.
