A few comments on pick clack.
First, you probably notice it more than any listeners would since you are right above the instrument and the clack does not bounce around in the box and get amplified the way the sound from the vibrating strings does.
Second, you might indeed be hitting the fretboard when you pick or strum, but that is probably the only technical "mistake" that one might make.
Third, although it might seem counter-intuitive, thinner picks make more of a clacking sound than heavier picks. Consider moving to heavier picks and holding them loosely rather than tightly.
Fourth, you might indeed reduce pick clack with leather or felt picks, but you will never be able to control those picks enough to play lots of single notes, something you may want to do eventually even if you are mostly strumming now.
And fifth, some of us don't hate the pick clack, so don't worry about it too much. I liken it to the sound of fingers squeaking as they move along the strings. It is a nice reminder of the tactile nature of the instrument. This is music being made by a person holding an instrument, not some digital creation made in a vacuum with no ambient noise.

As a musician, you have to keep one foot back in the past and one foot forward into the future.
