I have seen many Muslim individuals not knowing what to pray and how to worship Allah on the night of Qadar. Since the significance of this day is huge, most people are looking for nawafil that will provide the greatest blessings and rewards. Some may prefer reading the holy Quran all night, but I think that the following nawafil are useful.
1. Offer two rakat nafl. In each rakat, after Surah Fatiha, recite Surah Qadar once and Surah Ikhlas three times. This person is promised a place in the Heaven that stretches from east to west.
2. The Prophet (PBUH) also said that who offers two rakat naft on the Night of Qadar and recites Surah Ikhlas seven times after Surah Fatiha and also reads (Astaghfirul lahil azimal lazi la ilaha illahoal hiul qaiumo wa atubo alaih) seventy times after the prayer, Allah will forgive all his sins before he even gets up from his prayer mat.
Therefore, if you want to earn a place in Paradise and seek forgiveness, make sure you recite the nafl given above as I do.
