Frank,
A hold on a missed approach is entered just as any other hold. On an approach chart, it's often easier to visualize because the holding pattern is depicted, and it's drawn in relation to the facilities in use. It's all in one spot, so most of the time you can see at a glance what entry to use.
Don't get bound up over seventy degrees this or that. If it looks like you can enter direct, do so. If it looks like a teardrop will work, then do that. If a parallel gets your goat, go for it. Not a big deal. I tend to prefer direct or teardrop. Direct for obvious reasons, but if a course reversal is necessary to get established, especially at a time when cleanup checks are being conducted and there may be a higher cockpit workload, the teardrop places me farther from the fix and gives me a little more time to get established inbound at the completion of the turn.
Read the missed approach instructions. Then look at the depicted proceedure. If you brief yourself on this before beginning the approach, it will be much more simple. Most always you'll know at a glance what kind of entry you want to do. When I'm actually flying an approach, or supporting someone else flying an approach, I only stay one step ahead during the proceedure, for the most part. I'll advise the next turn and altitude. Once that turn and altitude is made, I'll advise the next.
When it comes time for the missed, I'll go for the initial turn and climb. When it comes time to enter the hold, it's just like every other part of the proceedure. The next turn will be XXX, altitude XXX.
