Drain and rinse the jackfruit, then use your hands to shred it into a pulled-pork consistency.
Crumble the tempeh into small, bite-sized pieces using your fingers.
Heat the olive oil in a large skillet over medium-high heat.
Add the shredded jackfruit and crumbled tempeh to the skillet, sautéing for 5-7 minutes until the edges are golden and slightly crispy.
Stir in the black beans, nutritional yeast, cumin, smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Cook for another 3 minutes, adding a splash of water if the mixture becomes too dry to prevent sticking.
In a small bowl, mash the avocado and whisk it together with the soy yogurt and lime juice until the crema is smooth and creamy.
Warm the corn tortillas in a dry pan or over an open flame for 30 seconds per side until pliable.
Divide the jackfruit and tempeh carnitas mixture evenly between the warm tortillas.
Top each taco with a generous dollop of the avocado crema and garnish with fresh cilantro.
