What other acts can I do that would be an ongoing charity (Sadaqah Jariyah) for my deceased father, besides printing booklets and donating to contribute to the building of mosques?

Filial piety does not cease with the parents' death; it continues through: praying for their mercy and forgiveness, fulfilling their will and covenant, maintaining kinship ties that are only connected through them, honoring their friends, giving charity on their behalf, and supplicating for them. This is based on the Prophet Muhammad's (peace be upon him) saying: "When a person dies, all his deeds cease except for three: a continuous charity, knowledge from which benefit is derived, or a righteous child who prays for him."
