Just put them in your addon's namespace. There's no reason to make everything a global. For example, if this is what you have now:

-- File A
function MyAddon_DoThings()
     print("Doing things.")
end

-- File B
MyAddon_DoThings()

Change it to:

-- File A
local ADDON, private = ...
function private:DoThings()
    print("Doing things without globals!")
end

-- File B
local ADDON, private = ...
private:DoThings()
