Preheat a skillet over medium heat. Rinse and drain the jackfruit, then shred it using a fork to mimic pulled texture.
In a bowl, combine the shredded jackfruit with smoked paprika, chili powder, cumin, garlic powder, salt, and pepper. Stir well to coat evenly.
Add the jackfruit to the heated skillet and cook for about 5-7 minutes until it heats through and slightly caramelizes.
Meanwhile, slice the tempeh into thin strips. Season with a pinch of salt, pepper, and a light dusting of smoked paprika.
In a separate non-stick pan, lightly sauté the tempeh strips over medium heat for about 4-5 minutes per side until golden and firm.
Warm the corn tortillas in a dry skillet or on a griddle until they become pliable.
To prepare the avocado crema, blend the avocado, nonfat Greek yogurt, lime juice, and a pinch of salt in a small bowl or blender until smooth. If desired, add a teaspoon of water to adjust consistency.
Layer each tortilla with a serving of spiced jackfruit, black beans, and sautéed tempeh.
Drizzle the avocado crema over the filling and sprinkle with chopped fresh cilantro.
Serve immediately and enjoy your delicious, protein-packed smoky jackfruit tacos.
