The simplest token in open zeppelin is the ERC20 https://github.com/OpenZeppelin/openzeppelin-solidity/blob/master/contracts/token/ERC20/ERC20.sol which you can copy an initialize by creating another contract inside that same file with your token name. For instance contract TokenExample {} inside there you setup your total supply, decimals, token name, token symbol and the owner of that total balance.

That’s how you create a token contract.
