Look for items you can turn a profit on and see what skills they need.

From the Eve Production Manager User Guide,

If you're just starting out as a producer and you don't have a lot of isk, managing your capital, margin and turnover are far more important than factory efficiency. In the short term, you will simply never max out your factory slots with high efficiency jobs until you're rather flush with capital. Instead, using the Market Research Report, you should look for high margin high turnover items so that you can more quickly build your capital. It's only when you have enough capital to max out your slots with your existing portfolio that you can then look to increase your produced isk per hour.

If I were a brand spankin' new producer today, I would start with the best cruiser, the best large rig and the best hauler and run with that for a couple weeks to gain experience and insight into my market. Expanding from there, maybe more cruisers and rigs. If my isk becomes too tight, I would consider reducing my build quantities in conjunction with preferring a higher minimum markup, building perhaps 5 of each cruiser rather than 10 so that my stock is still diversified, and perhaps a 7-10% minimum markup. As the isk begins to accumulate, maybe a capital rig or a very select battlecruiser. Battlecruisers are problematic to new producers as they are generally highly contested and require significant capital and good teams to do well. However, battlecruisers, then battleships, as well as POS structures and some high end mods are your ultimate goal.

Something that you can build with relatively low skills and that is (almost) always profitable is Light Neutron Blaster II (note - that's the tech 2 version, not the tech 1 version).

My alliance uses literally tens of thousands of these modules each month, and they are also heavily used in factional warfare, so there are always buyers.

Right now, the cost to run the invention jobs (one of the three main steps of building T2 modules) is higher than usual, but the job overall is still profitable.

As a major end user of these modules, I'm always looking to push the price on them down by getting more people building them.

Ditto for Magnetic Field Stabilizer II, although they are not a good thing to be building now IIRC.

I started out with T2 Drones. They are cheap enough to produce and will give you a good basic introduction to T2 manufacturing, they also sell really fast and the margin can be good. I went from drones into T2 ships and eventually into blueprints as well.

If you decide on using a POS then I'd look at using a small one if I was you. Apart from the cost benefit compared to the larger towers, you can rip it down in the unlikely event your corporation is wardec'd. Think about using a large tower when your potential loss from unanchoring array's starts to worry you and you need a more permanent presence.

I'd suggest trying out EVE IPH 3.1, it is an excellent tool for manufacturers, although it is a bit of a work in process atm because of the industry changes in Crius. Still, I'd give it a go though and get used to it because it is improving all the time.
