how to tweak my workout?

52yo female. lifelong athlete (on & off, tho). started pretty serious lifting a few months ago and i’m loving it! my only issue: i seem to be bulking, when what i want is to get stronger & leaner. i am def stronger, but… also noticeably bigger. i eat about 1500-1700 calories a day, don’t drink often, very little sugar, no processed food, etc. i’m doing 4 sets of 10 reps usually. 5 or 6 supersets (so, 10 to 12 different exercises). do i need to up my reps to 15 and lower the lbs i’m lifting? add more cardio (i do about 1 hr a week)? how do i tweak my workouts to get stronger and leaner but not bulkier?
