Using H1B when passport is lost

I came to the United States in 2005/06 and worked in the country on an H1B visa. I left USA within 7 months. Later, things happened in the following order:

1. While leaving USA, I forgot to take back my I797 document.
2. In 2009/10, my passport was stolen. So, the visa stamping on my passport was lost too. I don't have any copy of my stolen passport or visa.
3. I applied for a new passport while I was in India and after lot of running, I got my new passport.
4. At present I am in USA as a student (with an F1 Visa), which will expire in August, 2015

Now, I came to know that I can use my old approved H1B petition to work in the USA. Can you please tell me the process on how I can get my H1B status back?
