In a medium bowl, combine shrimp, olive oil, garlic powder, paprika, salt, and black pepper. Toss until shrimp are well coated.
Heat a large skillet over medium-high heat. Add the shrimp and cook for 2-3 minutes on each side, or until they turn pink and opaque. Remove from heat.
In a separate bowl, mix together the mayonnaise, sriracha sauce, and lime juice to create the spicy mayo. Adjust the sriracha to taste for desired spiciness.
To assemble the bowls, divide the cooked jasmine rice among four bowls. Top each bowl with cooked shrimp, shredded cabbage, diced cucumber, sliced green onions, and avocado. Drizzle with spicy mayo.
Serve immediately and enjoy!
