1)Lifting weights. You can basically do full body workouts in the first 2-3 weeks until you get back in the groove and make a good workout plan.
2)Cardio. Do sprints. They're slightly more entertaining than the jogging and they're more effective too. I used to do 20 minutes a day.
3)Diet. First of all, drink tons of water(water, not soda, not juice - which is almost as crappy as juice due to the tons of sugars in it and lack of natural vitamins due to the amount of time it spent in the box).
About food, eat as much as you can, but have the meals throughout the day. The foods you should eat should be high protein, low carbs foods. If you can't do without bread, find that bread that is high on fiber(it will improve your digestive system) and low on carbs. I can go on with other changes, but these are basic and you need to get these down before other things, I think.
This is what I did to get from 202lbs to 165lbs(and considering I have slightly more muscle than I had back then, I can say I lost around 50 lbs of fat - being pure fat and bone sucks lol). Now it's bulking time!!!
EDIT:BTW, the diet part is the most important.
