There are several strategies to repair and strengthen the metabolism, and you are wise to attempt this now, becuase if you don't you will suffer for it as you age.

1. You do need to eat a balanced diet that includes reasonable amounts of carbs, protein, and fat. As a vegetarian, you may find it challenging to find adequate sources of protein, but you MUST. You should have about 25-30% of your calories as protein with each meal. 1 protein gram = 4 calories. Do you eat dairy or eggs? There are many soy products out there other than tofu... you should look into them. Look for the "Amy's" brand of foods in your healthfood store - really wonderful foods that will help you accomplish this goal.

2. Consume more water and avoid other beverages. This will help you metabolize carbs and fat more efficiently. For your current weight you should drink at least 75 ounces of water daily. Measure it out at the beginning of the day to be sure you get through all of it!

3. Eat often throughout the day. 5 or 6 small meals is better than 3 big meals. The goal is to keep your blood glucose levels stabilized throughout the day. If you are experiencing spikes and drops in blood glucose levels your body will retaliate!

4. Don't reduce your caloric intake too much. Often, by simply strengthening your metabolic function your weight will resolve itself, especially since you are not that overweight and your extra pounds may be fluid retention.

5. Improve the quality of your food. Eliminate chemical additives and preservatives whereever possible. Avoid high sodium and high fat foods. Focus on complex carbs and avoid white flour (including pasta) and sugar products.

You mentioned "detox" - Do not take drastic steps and go on an all-juice diet for 3-5 days (or something similar)... not a good idea. Following the steps 2 and 5 above will detoxify the liver. It won't happen overnight, but afer some time you will feel like a new person.
