Season the shrimps: Peel and devein the shrimps, pat them dry with a paper towel, toss them with taco seasoning, garlic powder, onion powder, salt, pepper, and smoked paprika until evenly coated.
Cook the Shrimp: Heat a large skillet over medium-high heat. Add 2 Tbsp of olive oil to the pan. Cook the shrimp for 1-2 minutes per side until pink. Avoid overcooking to keep them juicy.
Make the Dressing: In a small bowl, whisk together the plain Greek yogurt, mayonnaise, lemon juice, taco seasoning, salt and pepper until smooth.
Warm the Tortillas: Heat tortillas in a dry skillet or wrap them in foil and warm in oven.
Assemble the Tacos: Pour half of the dressing over the coleslaw mix. Fill each tortilla with shredded purple cabbage, shrimp, green onions, jalapenos, and drizzle with dressing. Finish with lime wedges.
