It's important that you understand what a "toned" body is physiologically, it's easy to get a lot of bad/fuzzy/cute ideas, like that high number of reps -> toned, few heavy reps -> bulky, forget all of that, it's bullshit. It's all about the amount of fat and the amount of muscle tissue.
The first layer of the body to consider is your musculature, your muscles can get thicker or thinner, meaning stronger or weaker, you can't really affect the length of the muscles, that's determined genetically. Muscles can not be/look toned.
On top of the musculature is your fat layer, without this you would basically look like a redder version of the most extreme body builders, i.e. lots of veins and the muscle fibers being visible. The more fat you add, the smoother you look, first the veins and fibers disappear, then the separation between muscles disappear, so you can no longer see for example your bicep bulge. If you add even more fat you'll start to look like a molten cake, fat hanging on top of other fat and so on.
What do we need to achieve the toned look? You will need some muscle mass for the musculature to be visible at all, most females have too little muscle mass to achieve the toned look. The best way to increase this is the workout basically like a male body builder, it doesn't matter that your goals are different, your direction is the same but the distance is different so to speak :) Stop when you have enough muscles, this will take year(s).
Second, you need to adapt your fat amount, you need a moderately low amount of fat to achieve the toned look, not body builder low, but certainly lower than the average person. Your fat amount is determined by your diet and lifestyle, consumer fewer calories than you use and you'll lower the amount of fat.
