Making a mod collection

A mod collection that you can actually add to worlds involves making an empty mod then using the workshop's "Required items" (dependencies) feature to make it pull in any mods you wish.
This works fine with mods that themselves have dependencies too.

Go in %appdata%/SpaceEngineers/Mods/ (valid path that you can paste to folder address bar and press enter. don't search!)
Create a folder that will be your mod's name
Inside that mod folder create a folder called Data, this is required for the game to not crash when loading this empty mod.
Now inside the game at the mods window (any world -> options -> mods) you can select your local mod on the left and click Publish.
On the workshop page on the right you have Add/remove required items, click that to add dependencies.

And you're done, you can add this published "mod" to any world and it will bring all dependencies with it automatically.

Making custom world templates

If you want to go a step further, you can add things in the Custom Worlds section of the New World menu.

Go to SE's install folder (in steam you can rightclick -> properties, installed files tab and Browse button to open the folder)
Then go into Content and CustomWorlds
You can simply copy an existing world right here, or you can copy-paste one of the existing ones.

The existing ones have a .scf file that can be drag&dropped into a text editor to edit (.scf is assigned by windows for something else). This file is also not required so you're free to just delete it for your own clone.

Steam updates and validations of the game will not delete things so your worlds should be safe from that at least, but of course back up anything you don't want to lose from the plethora of ways one can lose files.
