In a bowl, stir together oil, lime juice, chili powder, cumin, garlic powder, salt, and pepper. Pierce chicken breasts with a fork. Place in a large Ziploc bag. Pour marinade over chicken. Let marinate for at least 30 minutes. 4 - 5 hours is ideal.
Preheat grill to medium heat. Brush grill with oil to prevent sticking. Place chicken on the grill. Cook for approximately 5 - 6 minutes per side, depending on the thickness of chicken. The internal temperature of the chicken should reach 165 degrees. Let rest for 5 minutes. Cut into bite-size pieces.
In a medium bowl, lightly mash avocados with a fork, leaving chunks, if so desired. Add diced onions, cilantro, jalapeno. Drizzle with fresh lime juice. Sprinkle salt and garlic powder. Stir. Taste and add more salt as needed. I tend to like my guacamole with some flavor so I add a little extra salt.
Heat skillet over medium heat and add a little oil to the skillet. Add tortillas and cook for about 1 minute per side or until pliable.
Fill each tortilla with chicken. Top with pico de gallo and guacamole. Top with cotija cheese and Mexican cheese, if so desired.
