My partner opened 1♦ and RHO overcalled 1NT. My hand was:
♠ - K8752
♥ - AT97
♦ - 7
♣ - 865

I did not feel I was strong enough to bid 2♠ with only 7 HCP; besides, this bid would ignore the 4 card heart suit. Double would be for penalty. I passed, and RHO made 1NT. At the other table, they made 3♥ our way. How can I show my partner what I have in the majors?

Many people use 2♣ is this auction to show the Majors... You then lose the 2♣ bid, but it is a very worthwile sacrifice, for hands just like these... You can even use a system over 1NT, that allows you to bid your partner's suit naturally.

From my notes with one partner:
1♦ - (1NT) - ?
X = Penalty
2♣ = Majors
2♦ = To Play; 5+♦
2M = Natural; To Play
2NT = To guard against a psych, 2NT is GF (Unless weak w/♣), Relay to 3♣
-3♣ = Forced
--Pass = Weak w/♣
--3♦ = ♦ Support; GF
--3♥ = Natural; GF
--3♠ = Natural; GF
--3NT = To Play

1♥ - (1NT) - ?
2♣ = Relay to 2♦ (Long ♦/♥ Support; Invitational/Long ♠)
2♦ = ♦ + ♠
2♥ = ♥ Support; To Play
2♠ = ♠ + ♣
2NT = To guard against a psych; GF (Unless weak w/♣); Relay to 3♣
-3♣ = Forced
--Pass = Weak with ♣
--3♦ = Natural; GF
--3♥ = ♥ Support; GF
--3♠ = Natural; GF
--3NT = To Play

1♠ - (1NT) - ?
2♣ = Relay to 2♦ (Long ♦/Long ♥/♠ Support; Invitational)
2♦ = ♦ + ♥
2♥ = ♥ + ♣
2♠ = ♠ Support; To Play
2NT = To guard against a psych; GF (Unless weak w/♣); Relay to 3♣
-3♣ = Forced
--Pass = Weak w/♣
--3♦ = Natural; GF
--3♥ = ♥ Support; GF
--3♠ = Natural; GF
--3NT = To Play

A lot of people play 2C majors here. It works well on hands like this, and if you have clubs you were probably gonna get outbid by majors anyways.

DBL is penalty and 2-level bids are not forcing. Your strength is no issue here.

After 1 of a minor by partner and a 1NT overcall by RHO, I respond as if partner had opened 1NT.

Thus, I would rebid 2♣ Stayman with the example hand.

I like to play 2Om (here 2♣) as both Majors, this hand is perfect for this treatment. And as Justin said: if you have ♣ then opps will outbid you in the Majors anyway.

over 1M-(1NT):

2♣=both majors (2-5, 3-5, 3-6)
2♦=good raise
2oM, 2M=just competitive
2NT=good raise with shape

over 1m-(1NT):

2♣=both majors
2♦=one major, good hand
2M=just competitive
2NT=good raise

this structure is a bit controversial because you lose the single raise of partner's minor, but it's not something you use a lot anyway.
