Google for it.

Neither supplies a model library.  It's a lot of work to keep it 
up to date.  So, you need to search the web for the model 
statements.

The most obvious answer is "google for 1n4004 spice model".  You 
will find several of them, not all the same.  They all should 
work with either ngspice or gnucap.

Since you need to ask, most likely you don't need the detailed 
model statement.  You can probably get away with using the 
defaults ..

.model 1N4004 D

If you want something better, but still not all of the details, 
look at the gnucap manual examples.  There is an example 
showing how to  determine IS of a diode experimentally.
