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 3-4 minutes, or until the shrimp are pink and opaque.
To assemble the bowls, divide the cooked jasmine rice among four bowls.
Top each bowl of rice with the cooked shrimp, sliced avocado, shredded carrots, cucumber, and green onions.
Drizzle the spicy mayo over the top and sprinkle with sesame seeds. Serve immediately.
