Preheat the oven to 400°F (200°C).
In a small bowl, mix olive oil, lime juice, cumin, smoked paprika, salt, and pepper to create a marinade.
Lightly coat the tilapia fillet with the marinade and place it on a parchment-lined baking sheet.
Bake the fish for about 12-15 minutes or until it flakes easily with a fork.
While the fish is baking, prepare the fresh slaw by combining shredded cabbage with a pinch of salt, pepper, and a squeeze of lime juice.
Warm the corn tortillas in a dry skillet for about 30 seconds on each side.
Assemble the tacos by flaking the baked fish onto each tortilla, topping with a generous serving of cabbage slaw, and drizzling with Greek yogurt.
Serve immediately and enjoy the balance of crispy fish and refreshing slaw.
