What you can do is have a table with two columns, one side with the NOC duties, and then on the other size you write in your own words what exactly you did.
For example, for the NOC "University Professor", one of the duties is "Teach undergraduate courses". Then you could write the list of courses that you taught: the course title, a brief description of the subject, the number of hours, perhaps the number of students.
Another duty is "conduct research", then you could list some of the recent projects you've been engaged on.
that's just a suggestion, of course.
