On the following map you can click on various districts in Fukuoka for a list of yatai stalls in the area.

You really don't need any map. If you can see Canal City, you can see the yatai directly across from there along the river. You can see

Most likely you can just close your eyes and follow the smell of the ramen.
There are other yatai as well in Nagahama, just northwest of Tenjin. You can get more info
