As said, take a good time to read up on some nutrition stuff. Things you could include are
Protein:
Eggs
Dairy
Chicken
Fish
Lean beef
Turkey
Ham
Carbs:
Pretty much any veggie and fruit. I don't think I need to list all of those
Whole grain bread
Oatmeal
Quinoa
Fats:
Dairy - full fat is okay just as long as your total saturated fat intake for the day is controlled
Olive oil
Canola oil
Avocado
Nut butter (peanut, cashew, almond, even sunflower seed etc.)
Eggs (I know they were listed already but they're a good source in both ways)
Nuts (particularly walnuts and almonds if you want to get picky)
Fatty fish - salmon and tuna
Just as some general stuff I can come up with here, try to hit somewhere in the range of 1g/lb of BW in protein intake, and fill the rest with the carbs and fats suggested. If you want a ratio to follow (though it doesn't matter assuming adequate protein), try something like P/C/F of 30/40/30 or even 30/50/20. Also, go to freedieting.com and figure out your maintenance. Take about a 15-20% deficit off there, or somewhere in the 500 calorie range. Use fitday.com (or others such as nutridiary.com or thedailyplate.com) to keep track of what you're eating. Those are the most important steps to take right now.
