Constitutional Amendament to allow prayer back into the schools

In order to get prayer back into schools, with the U.S. Constitutional Amendment, what steps and stages need to be taken?  I know the first step is to persuade a representative or Senator to introduce the bill, which give me two options to make a proposal. Both the Senate and House of Representatives each must have at least two-thirds of their members vote in favor of making the proposal in order for it to be considered. I am not sure of the next steps to take to gain endorsement.  I have to include factions of the national political landscape that would support this proposal as well as those that would likely oppose this new law. I can find a lot of information on why opposing the amendment, not much on enforcing the amendment.
