Well, you are right he didn't direct his men very well, as he let himself get charged in the flanks by elephants. Of course, I didn't use the elephants alone - they just disrupted the line, the thing that actually made the enemy break was my main battle line.

That's why I always keep my own heavy infantry on hand. Elephants can break off from infantry relatively easily (they just walk out), but enemy lines will be disrupted enough so that your own heavy infantry can mop up pretty easily.

Lining up a few onagers works against pretty much anyone

Fortunately for me, the AI doesn't like siege engines very much, so I didn't really have to think much about countering them effectively. Any tips on that?

Try hitting a group of upgraded Praetorian cohort with an armoured elephant column and you might be surprised; a lot of them will fall down but they'll just get back up again and keep fighting.
Yeah, playing with the Romans is easy precisely because their medium-level units are better and cheaper than anything your enemies can throw at you. At the worst case, a Roman can build four Pretorian Cohorts before I can pump out a single elephant. (They only need an imperial palace for those, while Seleucids need their best palace
and best stables.)
Of course, War Elephants will do nice as well. They will knock the praetorians down and keep running, while lighter cavalry does most of the killing. In my Seleucid game, war elephants actually make up the bulk of my Oversized Weapons Division.

That's one reason why it can be preferable to have masses of mediocre units than a smaller number of high-end units, unless you are fairly close to a large, well-equipped city under your control.
I find that my armies going to the far north usually end up using cheap, low-tech units. Even medium level ones from civilized nations can whoop barbarian ass easily, but you can retrain them on the fly as an added bonus.
