I don't think there are any ideal ratios for bulking but I don't think you can go wrong with sticking to whole foods. By doing this you can let the ratios take care of themselves.
Eat plenty of meats, whole eggs, fish, green veggies, cottage cheese, brown rice, sweet potatoes, and drink whole milk and quality protein shakes. Eating like this is high protein, low-moderate carb and moderate fat. Up your carbs a couple of days per week either on the weekends or once every 3-4 days.
