In a small bowl, mix soy sauce, hoisin sauce, garlic, ginger, sesame oil, sugar, and rice vinegar to make the sauce.
Place chicken into a bowl, pour sauce over chicken, and stir to coat. Marinate for at least 15 minutes.
Heat a large skillet over high heat, add 2 tablespoons peanut oil. Cook chicken until browned and cooked through, about 4-5 minutes. Transfer to a plate.
In the same skillet, sauté carrots, onions, mushrooms, and zucchini until tender-crisp, about 5 minutes. Remove and set aside.
In a separate large skillet, heat 0.25 cup peanut oil over medium-high heat. Add scrambled egg, cook for 20 seconds, then add garlic and green onions. Cook for 30 seconds.
Add cooked jasmine rice to the skillet with eggs, garlic, and green onions. Spread into an even layer and fry undisturbed for 3 minutes. Stir, then repeat for 10 minutes total.
Stir in soy sauce for rice, cook for additional 4-5 minutes until rice is fried and coated.
Add the cooked chicken and vegetables to the fried rice, stir to combine and heat through, about 2 minutes.
Serve portions topped with chopped green onions and Yum Yum sauce.
