Mix sriracha sauce, oyster sauce, teriyaki sauce, five-spice powder, hot sauce, and Sichuan peppercorns in a small bowl and reserve.
Heat oil in a medium pan over medium heat. Add shrimp and cook until mostly pink on the outside, about 3 minutes. Add the sauce and stir to coat shrimp. Cook until sauce is thick and sticky, 2 to 3 minutes more.
