Peel and dice the sweet potato into small, uniform half-inch cubes.
Heat the extra virgin olive oil in a large non-stick skillet over medium heat.
Add the sweet potatoes to the skillet and sauté for 8-10 minutes, stirring occasionally, until they are tender and golden brown.
Push the sweet potatoes to one side of the pan and add the ground turkey to the empty space.
Break the turkey apart with a wooden spoon and season the entire pan with smoked paprika, cumin, garlic powder, sea salt, and black pepper.
Cook the turkey for 5-7 minutes until fully browned and no pink remains, then toss everything together to combine.
In a separate small dry skillet, warm the corn tortillas for about 30 seconds per side until pliable and slightly charred.
Assemble the tacos by spooning the turkey and sweet potato mixture into the warm tortillas.
Top each taco with a tablespoon of Greek yogurt, finely diced red onion, and chopped fresh cilantro.
