I've seen it mentioned in discussions how the Saga had parts dubbed into English that had, in the original films, been sub-titled instead.

I'm ashamed to admit that after repeated viewings, this never dawned on me and I cannot recall which scenes people are referring to.

Can anyone tell me which parts were dubbed into English specifically for the Saga?

Or, perhaps provide a link to a thread where this was previously discussed?

There are a lot of them.

For instance, Vito on speaks English once or twice in the original film. But in the epic/saga, he speaks it much more as do his men.
