The base diet template won't change for someone with a physical job vs someone with a desk job, the calories will just need to be higher for the person with a physical job because they are expending much more calories throughout the day.
It's impossible for me to give you an exact recommendation on how many calories, protein, fat and carbs you should consume each day because I don't know your age, weight, height etc. but here is a offseason meal plan I wrote for one of my clients who has a physical job. You can use it as a template for your own diet.
