What you're calling "toning" is really a product of two things: 1) dropping enough fat so you can see the muscle, and 2) building muscle so more of it can be seen. Do you feel like you need to do 1, or 2? If 1, start a food plan with a decent (but not killer) deficit. If 2, start one with a similar surplus. Eat whole, natural foods, and weigh and track everything that goes into your mouth.
Edited to Add: Also critical is matching your food intake to your workout intensity. If the latter is too high, and the former too low, you'll be miserable because you'll be hungry all the time (and more likely than not you'll eat those calories back whether you want to or not to recover). If the former is too high, then you'll be dirty bulking, with a lot of the weight you'll be putting on will be fat, not muscle.
Edited to further add: You'll get more bang for your buck if you do 1 first, because people with lower body fat % often appear more muscular than people who actually do have more muscle.
