Hi Shiprai,
The primary requirement to be a trainer is good communication skills and loads of self confidence. If you have these, then focus on those topics that you are familiar with, confident about, passionate about or have a good grounding in. Keep updating yourself by reading extensively and start outlining the broad course contents keeping in mind the type of audience you are likely to address. In particular pay attention to the type of exercise, examples, activities that you will use during the program to reinforce a point or make the learning relevant.
If you have no corporate training experience, ideally take a few sessions for post graduate students in colleges or for social service clubs like Lions and Rotary's so that you gain in experience and also can fine tune your material. Once you are confident, approach a few corporates and the first few training programs are vital for future reference and for your own confidence.
If possible attend a Train The Trainers (TTT) program and also be a participant in a couple of corporate training programs so that you have a better understanding of how the sessions are conducted. I would also urge you to also go through the syllabus of Indian Society for Training and Development headquartered in New Delhi and I am sure if you do the course it would add weight to your resume and possibly help you get a few opportunities in T&D in the corporate world.
