I was the plaintiff in a civil and judgement was entered by the judge yesterday. I need to know the next step in the process.

The next step is collecting on the judgment, which typically involves garnishing wages and bank accounts.  If you don't have the information about where they work or bank you can summons them to court to answer debtor interroagories, which is basically just you asking them any questions for this information.  You can also file your judgment with land records to put a lien on any real estate they might own and it's possible to seize any items of value they might have.  You may want to hire a collections lawyer to help you out with this.
