Essential: mining lasers to generate fragments.
The medium ones are most efficient. The Asp can sustain one, but you can add a second and let the distributor drain.
Essential: refinery to refine fragments.
You want at least 3 bins that can be matched to the current asteroid you are mining. Everything more is convenience.
Be aware that a 2A refinery offers more bins than an equivalent cargo rack, while a 4A offers less bins than an equivalent cargo rack.
(bins are capacity - I would opt for overall more rather than wasting energy on convenience)
An A grade prospector limpet controller for maximum fragment yield per asteroid.
Class 1 will suffice. If you want to use them to find asteroids quickly as well a larger class that allows more active ones will increase your prospecting rate.
The best power distributor you can get for maximum mining laser time.
If you want to be better than A grade, charge enhanced modifications are the best.
One active collector limpet per WEP megawatt. Maybe a few more so you don't have to position yourself too perfectly.
D grade will suffice since fragments are always created within 500 m mining laser range.
Thrusters. You will have to move between and around asteroids a lot. You don't want that to take too much time, so take the best.
A grade power plant. Mining lasers generate a lot of heat. This will handle it best.
Shields and double chaff. Even if you don't anticipate hostile encounters you will most likely run into them eventually. Better safe than sorry.
Cargo racks to bring limpets and refine bins into.
The rest (FSD/weapons/boosters/...) as you need it.

How do you feel about Type 7?
Worst miner out there. Don't do it.
