The traditional Catholic night hour of Compline makes a very good banishing and protection ritual. I prefer the older translations, but the modern rite keeps most of the important prayers and is workable. The centerpiece is Psalm 91 (modern numbering) which is a protection rite in itself.

I use the closing prayer to open my morning and evening ritual.

Visit we beseech the O Lord this habitation, and drive far from it all the deadly power of the enemy; let thy holy angels dwell with us to preserve us in peace; and let thy blessing be upon us always. Through Jesus etc...

Psalms 27 and 42 among others can be used as protection rituals.
