Two basic plans. Cold turkey: bind yourself & send baby to others to bottle feed until they will for you. (painful & frustrating for both but some do ok.) gradual: drop a feeding every day or two, using bottle instead. At some point body drops supply & you can accelerate coming off. (less pain).
Weaning. Weaning your child is a personal choice, but the American Academy of Pediatrics that you breastfeed for at least a year.
