In order to relight the candle without directly flaming the wick is as simple as igniting the smoke. Impossible! No, nothing is impossible. Once you light the candle normally with your piezoelectric lighter (piezo lighter) or matchstick or whatever, blow the candle out. Then watch the smoke drift into the air. Ready your lighter or match again, but this time don't strike the wick, strike the top of the smoke stream. Instantly, the smoke will catch fire and burn downward until it reaches the wick itself and then — your candle is once again lit.
