Drain and rinse the jackfruit thoroughly. Using your hands or two forks, shred the jackfruit pieces, removing any tough cores.
Heat olive oil in a large skillet over medium heat. Add diced onion and cook until translucent, about 5 minutes.
Add minced garlic and cook for another minute until fragrant.
Stir in the shredded jackfruit, chili powder, cumin, smoked paprika, and oregano. Cook for 2-3 minutes to toast the spices.
Pour in the vegetable broth, reduce heat to low, and simmer for 15-20 minutes until the liquid is mostly absorbed and the jackfruit is tender.
Use a fork to shred the jackfruit further as it cooks, creating a texture similar to pulled meat.
Turn up the heat to medium-high and cook for an additional 5 minutes to create some crispy edges.
Warm the tortillas and assemble your tacos with the jackfruit filling and your chosen toppings.
