If you voted using the ARK Desktop client, you will see payouts as incoming transactions. How the delegate you voted for pays out is really up to him. Some pay out daily, some weekly, monthly, etc. Not sure if it's your case, but some people who vote with small amounts, it's not work for the delegate to pay if the payout is small and gets eaten up by transaction fees.
You can use the calculator here to check on your expected payout along with when your delegate payout to his/her voters: http://pool.arkno.de/calculator.php
