After you have finished the main plot and defeated the Elite Four, go to Lake Valor with a Pokemon that knows the HM Surf. Surf to the center of the lake, where there will be a small island. Go inside the cave (Valor Cavern) and Azelf will be an interactable ledgendary there. You can fight and capture him/her/it.
