I am surprised you were admitted on F-1 since you are married to a US citizen. I hope you did not lie to any questions posed to you at the time of entry.

The requirements and forms for family based immigration are on the USCIS website. If you have no issues in your background, you and your spouse should be able to complete them yourselves. If you have difficulty, engage an attorney. The US will recognized marriages properly registered in India; you do not need to do anything else to register your marriage in the US. However, if you did not complete all of the formalities in India, consult an attorney to determine the best strategy for your specific situation.
