How can I compare "Mother Night" by Vonnegut and "Song of Solomon" by Morrison in terms of Postmodernism?
Read all of this carefully:

Whenever you are writing a comparison/contrast paper (paragraph, essay, research paper), you need to plan it out very carefully on paper first.
Try this: Go through each work with those concepts in mind and make two lists -- actually lists on two pages, one page for Vonnegut's work and one page for Morrison's. Then put them together in this order:
1. Intro
2. All about topic A
~~~2A. detail 1
~~~2B. detail 2
~~~2C. detail 3
~~~2D. detail 4
~~~2E. detail 5
3. All about topic B
~~~3A. detail 1
~~~3B. detail 2
~~~3C. detail 3
~~~3D. detail 4
~~~3E. detail 5
4. Concl.
The number of details for each topic will vary depending on your main points. I would include comparisons (how they are similar) in the introduction and conclusion, but sections 2 and 3 and all those details will be stating and explaining how they are different.
There are two recognized patterns for writing comparison/contrast papers. One is casually referred to as "zig-zag,” but can be very confusing for the reader if you don’t use transitions effectively. The other is topic-by-topic (which is what I've outlined above) and is much easier for the reader to follow.
