Hi, Michael. 

“Theory of Change” and “Logic Model” mean slightly different things.  I have never needed a Theory of Change diagram (they don’t have set templates), but I have used Logic Models. 

I strongly recommend swimlanes (although in the example below, I hid them).  They not only track different dimensions over categories / phases, but (if you do not get too fancy) allow cross-linking.  Here’s an example, used in getting a grant for https://docs.fakenewsfitness.org: 
 

Here is what it would look like from a full swimlane example for a project I’m involved with, Resilient Greenfield, using SIPOC (which was crazy overwhelming so I did not decide to use it):

For different varieties, within Lucid, search the templates for “Swimlanes”.  Hope this helps!
