Eggs (in baking, as a binder)
1 tbsp ground flax seeds, mixed with 2-3 tbsp water, make a slurry and let it sit. This formula substitutes for one egg, adjust according to
recipe.
Soy sauce/Tamari
try coconut aminos (available online or at natural foods stores)
Flour
A wide variety of substitutes exist, try almond flour/meal, garbanzo flour, or rice flour
Sweetener
Applesauce, pear, pumpkin or sweet potato purée can add a touch of sweetness.
Dairy
Almond, hemp, rice, and coconut milk, also soak cashews overnight and blend to create a dairy based sauce, including cream cheese.
Citrus
This is a tricky one, try a splash of apple cider vinegar or bright fresh herbs like lemon grass, parsley, or tarragon. Tart Granny Smith apples and tamarind paste
can also give a recipe the “lift” that citrus usually provides
