[Qgis-developer] How do I change the symbol and its size from a provider?

I'm writing a plugin/provider that's similar in functionality to the 
delimited text plug in.  Things are working well, but I need to change 
the size, color and possibly the symbol itself when I add a point to the 
map.  I've been unable to determine a method of doing so other than 
going to the symbology tab on the layer properties dialog.  I want the 
change to happen automatically via the provider code.  Can anyone help out?
