Remove stems and seeds from dried chiles. Toast in a dry skillet for 30 seconds per side until fragrant. Add to slow cooker.
Heat oil in a skillet and sauté onion and garlic for 4 minutes. Add bay leaves, cinnamon, oregano, cumin seeds, coriander, and tomato paste. Cook 2 more minutes. Transfer mixture to the slow cooker.
Add chicken broth, apple cider vinegar, and soy sauce. Stir to combine. Season chicken breasts with salt and pepper and place on top.
Cover and cook on low for 4 hours or high for 6 hours, until the chicken is very tender.
Remove chicken, shred it with two forks, and discard bay leaves. Blend the sauce until smooth. Taste and adjust seasoning. Mix a bit of the sauce into the shredded chicken.
Warm tortillas in a dry skillet. Fill with birria chicken and top with cheese, onion, cilantro, and lime juice. Serve with remaining birria sauce for dipping.
