In a small bowl, mix together the mayonnaise, sriracha sauce, and lime juice to make the spicy mayo. Set aside.
In a large skillet, heat the olive oil over medium heat. Add the shrimp, garlic powder, paprika, salt, and pepper. Cook for 2-3 minutes on each side, or until the shrimp are pink and cooked through.
To assemble the bowls, divide the cooked jasmine rice among four bowls.
Top each bowl with the cooked shrimp, sliced avocado, shredded carrots, cucumber, and chopped green onions.
Drizzle the spicy mayo over the top and sprinkle with sesame seeds. Serve immediately.
