@astha, first of all see the Berin's answer which is full of essential and very useful information about nutrition. If this general overview is not enough for you I would just suggest to find some fitness diet on the internet.
EDIT HERE: One question arose today and you can get some inspiration there: Any advice for improving my diet chart?
As I said in the comment, please make your breakfast bigger and more various than only one pancake. Eat some yogurt, cereals, fruit. Put another meal between your breakfast and lunch and one more between lunch and dinner. So you will end up with at least 5 meals per day! I don't know whether your diet is really strict as you mentioned but if it is you need to stop it and start feed your hungry body with essential nutritions immediately!
It's something like -- your body is speaking to itself: "Oooh, I haven't enough food... well, if I'd like to survive, I need to start store any single molecule of fat!"
Drinking a tea (green is better choice) should be boosting your metabolism. That's great, approved :)
Psychological point of view: At first, I would focus rather on balanced diet than on losing weight. You need to internally know that you are ok, fit and healthy. And you will not be like that with you current diet. Sorry, that's very simple and obvious fact.
After that you can start do some experiments or you can even workout harder because you will have more power. You will see -- better food basically give you more power. Then, you can workout harder and your body will start changing itself. As Berin said, more muscles will consume more calories so you will start to losing fat.
And consider the fact that most men don't like skinny women. They like women in a good fitness shape with a strong core and unobtrusive amount of muscles. The best way I can see here is to continue with your exercise routine and possibly go a little bit beyond your current "comfort zone". Yoga is fine for stretching. Try something "harder", for example jogging could be great as well as swimming.
I can see you are active woman, that's very good! So change your diet properly, be happy with the healthy body and do sport on your 100 % edge :)
