With Kindred you should always start with the W, as long as no invades or similar happen at level 1, as this deals the most damage and even heals. Then skill the Q, as it gives you an AoE autoattack, additional attack speed, a dash and even an autoattack reset. Finally, skill E, as this is particularly important when fighting other champions. Since Kindred deals most of her damage via her autoattacks, you should max the Q first, then the W and finally the E. And as with most champs, you should always skill the R as soon as this is possible.

Combos:

Since Kindred is a very autoattack-based champion, her combos are anything but complex. The only important thing to consider is her animation cancels, but since neither her W nor her R have a casttime, there’s little to consider. The most important things are that you should always do the E immediately before an autoattack, the W ideally only after you have used your Q to take the maximum cooldown reduction with you and that you always use the Q as an autoattack reset to cause maximum DPS.

A standard combo looks like this: E-AA-Q-AA-W-AA-Q : First you cast E on the target so that they are slowed and you deal extra damage after 3 autoattacks. Then immediately follow up with the autoattack and Q for the extra autoattack. Then cast W and keep doing autoattacks until your Q is ready again.
