I'd start with a basic dumbbell routine like this one:

For each exercise, start with a light warmup set, rest as much as you need, and increase the weight on the next set until you're familiar with how heavy your body can handle (it may vary by day).
I found that weightlifting became more intuitive to me when I started thinking in terms of movements (e.g. push, pull, hinge, squat) more than body parts. Routines like this one allow you to get comfortable with these basic movements.
