Prepare for a long reply:
A typical manga-ka (or even normal novelists for that matter) would first present their ideas to the main publisher they are contracted with.
If the publisher deems his story to be well enough to be serialized on a weekly/monthly magazine, they will offer him a fixed per-page amount. Most of the time, they average around 3,000 yen per page. More well established manga-kas (which are rare) will get offers of 10,000 yen per page.
A typical serialization is about 15-20 pages per chapter on each serialization. So, if you are a manga-ka, you will be paid 3,000 x (15~20) = 45,000~60,000 yen per chapter.
Now comes the difficult part...publishers versus manga-ka royalties.
Say that you have stocked up enough chapters on the serialization to combine them into one volume tankoubon manga (usually 6-8 chapters per volume). Most manga tankoubons retail for 390 yen and up per volume.
The publisher will then decide to go ahead to make a single volume, but they also have to find out how many copies they want to make. The minimum qty is 10,000 copies, but if your manga serialization is doing good, it is expected that the publishers will make more copies of them to keep up with demand. The amount of royalties from manga are fixed at 10% from this amount of copies the publisher decides to print to the manga-ka.
So say that you have compiled 7 chapters from the serialization to make a single volume. The publisher checks your ratings, and finds that you are doing pretty well - so they decide to make 50,000 copies of your manga on the initial run. Each manga will be sold for 390 yen (the approximate value of one manga released from Shueisha). Therefore, your take is: 10% of 390 yen = 39 yen x 50,000 copies = 1,950,000 yen.
But then, wait. Your manga was so popular that when they sold it at stores, the initial press became all sold out. The publisher then decides that 50,000 copies weren't enough, so they order 50,000 more copies to keep up with demand. You get another 1,950,000 yen.
If you buy Japanese manga, you can check which press-run your manga is on the back of the book...you'll be surprised that some really popular titles that have been serialized for over ten years will be at their 20th or 30th press copy (of course if you decide to sell your manga at a used book store, they will offer you more money the earlier the press copy is).
So you continue your serialization and you get paid the basic 3,000 yen per page. You accumilate another 6 or 7 chapters to make volume two of your manga. This time, the publisher decides to start the initial press run at 100,000 copies since it did so well in your first volume. So once again, 10% of 390 yen = 39 yen x 100,000 copies = 3,900,000 yen in royalites to you.
This is basically it for the manga tankoubon royalties. All others are negotiated between the author, publisher, and the secondary company. So, if your manga is popular enough to spawn an anime series and merchandise, it is all negotiable. Most likely though, the publishers will do the dealing in place of you unless you happen to be a big name artist.
A. Manga-kas get paid roughly 3,000 yen per page for serialization
B. Royalites are paid in: the price tag of the book x percentage of royalties [usually 10%] x amount of copies that the publishers print
