Pat the shrimp dry with a paper towel to ensure a perfect sear in the pan.
In a small bowl, whisk together the chipotle powder, smoked paprika, garlic powder, sea salt, and black pepper.
Toss the shrimp in the spice blend until every piece is evenly coated.
In a medium bowl, combine the shredded cabbage, Greek yogurt, and the juice of half a lime to create a zesty, creamy slaw.
Heat the olive oil in a large skillet over medium-high heat.
Add the shrimp to the skillet and cook for 2-3 minutes per side until they are pink, opaque, and slightly charred.
While the shrimp cooks, warm the corn tortillas in a dry pan or over an open flame until they are soft and pliable.
Slice the avocado and finely chop the fresh cilantro.
Assemble the tacos by layering the lime slaw, smoky shrimp, and avocado slices into the warm tortillas.
Garnish with fresh cilantro and serve immediately with the remaining lime wedges.
