Designing/looking for a circuit board for a vaporizer
sorry if the flow doesn't quite make sense, this is a summary (mostly copy paste) of Q&amp;A that occurred in the comments of the original question

As Dave Tweed mentions (he's a good bloke) this is a HUGE power output for such a small power source. Fix that part of your spec first. Next I suggest you find some kind of IC that can do constant current controlling for such large currents - 10A is quite high on the scale of power controllers for normal use (not huge industrial stuff) you could use Current Shunt Monitor ICs like the Texas instruments INA138 to help display "Power" usage, while the microcontroller you choose can read the voltage input using its ADC

The issue with such high currents is the power electronics behind it is perhaps out of your capability.. I've been designing and successfully made some pretty crazy stuff, including a 120A pulsed LED strobe array, but they were for short on-times to allow heat dissipation. 

The control circuitry if you use an IC like this: cds.linear.com/docs/en/datasheet/37411fe.pdf 
will be difficult to get right the first time, if you have no experience. That IC can control up to 20A and 10V output by the way, but it costs $10 alone.

Because you are using battery power, perhaps look at the Texas Instruments line of "Simple Switcher" high efficiency converters with 1A output, and lots of nice protection in them. They will take anything from 8-40V and give you nice 5V 1A output. follow reference designs and you will be safe...

Be extremely careful with the LMZ31710 if you plan to use it; read every single word of that datasheet. For example, making sure cycle-by-cycle current limit is used rather tha hiccup fold-back mode. You will need pretty hardcore thermal relief, and I suggest putting a fan on it or something. please note the IC's package is going to be extremely hard for an unskilled solderer to place onto a PCB. The device does indeed fullfil all your requirements, but again, holy crap please take it slow and use the reference designs. dont do 10A loads (effectively shorts) first. staged testing over long times! There are much cheaper alternatives to that IC but the circuitry will be complicated (using current shunt monitors, and MOSFET power switching your own way. will have much less cool protection circuitry though..)

For the power monitoring side of things, you can easily make your own - like i said earlier a current shunt monitor IC from Texas Instruments INA138 will give you a voltage output directly related to current through the sense resistor, and a simple microcontroller can read the input voltage, and you do some maths on a controller and display on whatever little LED/LCD screen you can buy for cheap. there are lots on the market, just find one that is simple SPI or software serial.
